- 2 false 1
Correct answer: D
Explanation:
The length of the element with index 0, {0, 1, 2}, is 3. Output: 3The element with index 1, {3, 4, 5, 6}, is of type array. Output: trueThe element with index 0, {0, 1, 2} has the element with index 1: 1. Output: 1 The length of the element with index 0, {0, 1, 2}, is 3. Output: 3
The element with index 1, {3, 4, 5, 6}, is of type array. Output: true
The element with index 0, {0, 1, 2} has the element with index 1: 1. Output: 1

Question 4
Given:
What is the result?
- 6564
- 6554
- 6566
- 6565
Correct answer: A
Explanation:
Within main z is assigned 6. z is printed. Output: 6Within doStuff z is assigned 5.DoStuff2 locally sets z to 4 (but MyScope.z is set to 4), but in Dostuff z is still 5. z is printed. Output: 5Again z is printed within main (with local z set to 6). Output: 6Finally MyScope.z is printed. MyScope.z has been set to 4 within doStuff2(). Output: 4 Within main z is assigned 6. z is printed. Output: 6
Within doStuff z is assigned 5.DoStuff2 locally sets z to 4 (but MyScope.z is set to 4), but in Dostuff z is still 5. z is printed. Output: 5
Again z is printed within main (with local z set to 6). Output: 6
Finally MyScope.z is printed. MyScope.z has been set to 4 within doStuff2(). Output: 4
